i just got the idea that with ati trueform we can realtime meshsmooth objects. realtime meshsmoothing is at most used in metaball-visualisation.. can't wait for my radeon 8500 to test this http://www.opengl.org/discussion_boards/ubb/wink.gif if it works, you soon will get a geomorph demo with completely smooth mud you bomb trhough http://www.opengl.org/discussion_boards/ubb/wink.gif

(and 3d textures are very nice for visualisation http://www.opengl.org/discussion_boards/ubb/wink.gif)

now.. is there an ati-ext for gl yet for trueform? i'll go take a look now http://www.opengl.org/discussion_boards/ubb/wink.gif

You are looking for GL_ATI_PN_TRIANGLES (http://oss.sgi.com/projects/ogl-sample/registry/ATI/pn_triangles.txt) . There is a small sample on our devrel site also. You can find it and some others here (http://www.ati.com/na/pages/resource_centre/dev_rel/glsamples.html) .

BTW, not many people have done much with it, but the extension can also be used to just tessellate a triangle to get more vertices for it. In other words, there is more there than just n-patches.

i did not have done anything with it yet (like most of the people) because there are not much people yet owning an ati 8500. right? but soon i will, yeah! then i will rock on it http://www.opengl.org/discussion_boards/ubb/wink.gif

The weird thing is, I picked up an 8500 at Best Buy for less than $300 about two months ago. There was no line (or even empty shelf space) or anything, yet everybody complains how hard they are to get.

Now, if my ATI GL compatibility problems could only be solved, I'd be happy as a clam...

The problem is mostly in Europe where almost no Radeon 8500 has been seen. I've been waiting for cards to arrive since release but have yet to get one. Finally last week some Inno3D Radeon 8500 cards got in stock in one webshop here in Sweden, so I've ordered one of those, I hope I will recieve my card today. I really wanted to ATi retail version, but couldn't wait anymore, so I settled for third party.

yeah.. if i would have known that getting an ati here is so difficult i would have taken the one i've seen november standing around in a store http://www.opengl.org/discussion_boards/ubb/smile.gif too bad..
